Solution

The correct option is A

Blood pressure, pulse, cardiac output.


The 3 variables which measure the efficiency of the cardiac cycle and the heart’s pumping activity are blood pressure, cardiac output, and pulse. The pulse tells us if the SA node is functioning efficiently, the blood pressure tells us if the heart is pumping at the right pressure, and the cardiac output which refers to the total output of the heart (for example, in liters per min.), tells us if the needs of the body are being met by the heart.
